Description

本開示は、太陽電池モジュール用補強部材及び太陽電池モジュールに関する。   The present disclosure relates to a solar cell module reinforcing member and a solar cell module.

太陽電池モジュールは、一般的に太陽電池パネルと、当該パネルの端縁に沿って設置されたモジュールフレームとを備える。太陽電池パネルは、複数の太陽電池セルがガラス板等の保護部材で挟持された構造を有するが、受光面側から荷重が加わったときに当該荷重によって撓みが発生する場合がある。特に、モジュールの軽量化を図るため、保護部材の厚みを薄くした場合には太陽電池パネルの撓みが発生し易くなる。かかる状況に鑑みて、モジュールの裏側に補強部材を配置して太陽電池パネルを補強した太陽電池モジュールが開発されている（例えば、特許文献１参照）。   A solar cell module generally includes a solar cell panel and a module frame installed along an edge of the panel. The solar battery panel has a structure in which a plurality of solar battery cells are sandwiched between protective members such as glass plates. However, when a load is applied from the light receiving surface side, the load may be bent due to the load. In particular, when the thickness of the protective member is reduced in order to reduce the weight of the module, the solar cell panel is likely to be bent. In view of such a situation, a solar cell module in which a reinforcing member is disposed on the back side of the module to reinforce the solar cell panel has been developed (see, for example, Patent Document 1).

国際公開２０１１／０９０１６０International Publication 2011/090160

ところで、太陽電池モジュールの裏側に設置される補強部材には、太陽電池パネルを裏側から支持してパネルの撓みを十分に抑制でき、且つ構造が単純で製造コストが安価であることが求められる。また、補強部材は軽量であることが好ましい。従来の補強部材は、これらの要求に対して未だ改良の余地がある。   By the way, the reinforcing member installed on the back side of the solar cell module is required to support the solar cell panel from the back side and sufficiently suppress the bending of the panel, and has a simple structure and low manufacturing cost. The reinforcing member is preferably lightweight. Conventional reinforcing members still have room for improvement with respect to these requirements.

本開示の一態様である太陽電池モジュール用補強部材は、太陽電池パネル、当該パネルの第１の端縁に沿って設置された第１フレーム、及び第１の端縁に対向する第２の端縁に沿って設置された第２フレームを備え、各フレームの下部にモジュールの内側に張り出した内鍔部がそれぞれ形成された太陽電池モジュールの裏側において、第１フレームと第２フレームとの間に架設される長尺状の補強部材であって、各フレームの内鍔部にそれぞれ固定される一対の脚部と、各脚部にそれぞれ立設し、太陽電池パネルの裏面に対して略垂直に配置される一対の立壁部と、各立壁部の上端部同士を連結し、太陽電池パネルの裏面に近接又は接触した状態で当該裏面に沿って配置される天板部とを備える。   A reinforcing member for a solar cell module according to an aspect of the present disclosure includes a solar cell panel, a first frame installed along a first end edge of the panel, and a second end facing the first end edge. A second frame installed along the edge, and on the back side of the solar cell module in which an inner collar portion projecting inside the module is formed at the lower part of each frame, between the first frame and the second frame A long reinforcing member to be erected, a pair of leg portions fixed to the inner flange portion of each frame, and standing on each leg portion, substantially perpendicular to the back surface of the solar cell panel A pair of upright wall portions to be arranged and upper end portions of the upright wall portions are connected to each other, and a top plate portion arranged along the back surface in a state of being close to or in contact with the back surface of the solar cell panel.

本開示の一態様である太陽電池モジュールは、モジュールの裏側において第１フレームと第２フレームとの間に架設された上記太陽電池モジュール用補強部材を備える。   The solar cell module which is 1 aspect of this indication is equipped with the said reinforcement member for solar cell modules erected between the 1st frame and the 2nd frame in the back side of the module.

本開示の一態様である太陽電池モジュール用補強部材は、構造が単純で製造コストが安価でありながら、太陽電池パネルの撓みを十分に抑制することができる。   The solar cell module reinforcing member according to one embodiment of the present disclosure has a simple structure and low manufacturing cost, but can sufficiently suppress the bending of the solar cell panel.

本開示の一態様である太陽電池モジュール用補強部材は、一対の脚部、一対の立壁部、及び天板部からなる単純な構造でありながら、太陽電池パネルの撓みを十分に抑制することができる。本開示に係る補強部材は、例えば１枚の金属板を曲げ加工して製造することが可能であり、従来の補強部材よりも安価に製造できる。詳しくは後述するが、従来の補強部材は、一般的に断面略エの字形状を有し、曲げ加工よりも製造コストの高い押し出し成形で製造される。また、本開示に係る補強部材は、断面略エの字形状の補強部材と比べて耐荷重性に優れた構造を有する。このため、補強部材の厚みを薄くして軽量化を図ることができる。   The reinforcing member for a solar cell module according to one aspect of the present disclosure has a simple structure including a pair of leg portions, a pair of standing wall portions, and a top plate portion, and sufficiently suppresses the bending of the solar cell panel. it can. The reinforcing member according to the present disclosure can be manufactured by bending a single metal plate, for example, and can be manufactured at a lower cost than a conventional reinforcing member. As will be described in detail later, a conventional reinforcing member generally has an approximately letter “E” cross section, and is manufactured by extrusion molding, which is higher in manufacturing cost than bending. In addition, the reinforcing member according to the present disclosure has a structure superior in load resistance as compared with a reinforcing member having a substantially square cross section. For this reason, the thickness of the reinforcing member can be reduced to reduce the weight.

The module frame 20 is preferably constituted by a plurality of frames 20 a, 20 b, 20 c, and 20 d installed along the edge of the solar cell panel 11. Each frame is connected to an adjacent frame using a corner piece or the like, for example, and is installed so as to surround the four sides of the solar cell panel 11. Each frame is a long member obtained by extruding a metal material such as aluminum.

モジュールフレーム２０は、平面視略矩形状の太陽電池パネル１１の一方の長辺（第１の端縁）に沿って設置されたフレーム２０ａと、一方の長辺に対向する他方の長辺（第２の端縁）に沿って設置されたフレーム２０ｂとを有する。本実施形態では、フレーム２０ａ，２０ｂに、同じ形状、寸法を有する共通の部材が適用される。フレーム２０ａ，２０ｂの下部には、モジュールの内側に張り出した内鍔部２４ａ，２４ｂがそれぞれ形成されている。内鍔部２４ａ，２４ｂは、例えばフレーム本体２１ａ，２１ｂの下部からそれぞれ延出する。図１Ｂに示す例では、太陽電池パネル１１の短辺に沿って設置されるフレーム２０ｃ，２０ｄにも内鍔部２４ｃ，２４ｄがそれぞれ形成されている。   The module frame 20 includes a frame 20a installed along one long side (first edge) of the solar cell panel 11 having a substantially rectangular shape in plan view, and the other long side (first) facing the one long side. 2 edge) and a frame 20b installed along the edge. In the present embodiment, a common member having the same shape and size is applied to the frames 20a and 20b. Inner flange portions 24a and 24b projecting inside the module are formed at the lower portions of the frames 20a and 20b, respectively. The inner flange portions 24a and 24b extend from the lower portions of the frame main bodies 21a and 21b, for example. In the example shown in FIG. 1B, the inner flange portions 24c and 24d are also formed on the frames 20c and 20d installed along the short sides of the solar cell panel 11, respectively.

The reinforcing member 30 is a bar fixed to the frames 20a and 20b, and is preferably provided in a state of being substantially in contact with the back surface of the solar cell panel 11. The reinforcing member 30 supports the solar cell panel 11 from the back side so that the solar cell panel 11 is not greatly bent by the load applied from the light receiving surface side of the solar cell panel 11 as described above.

本実施形態では、太陽電池パネル１１の裏面に沿って１本の補強部材３０が設けられている。補強部材３０は、複数設置されてもよいが、軽量化、材料コスト削減等の観点から、１本であることが好ましい。補強部材３０は、フレーム２０ａの長手方向中央部からフレーム２０ｂの長手方向中央部に亘って設けられている。即ち、太陽電池モジュール１０は、太陽電池パネル１１の長辺方向中央部を通り、短辺方向に沿って設けられた１本の補強部材３０を備える。補強部材３０は、例えばフレーム２０ｃとフレーム２０ｄとの間に架設され、太陽電池パネル１１の長辺方向に沿って設けられてもよいが、軽量化、材料コスト削減等の観点から、パネルの短辺方向に沿って設けられることが好ましい。   In the present embodiment, one reinforcing member 30 is provided along the back surface of the solar cell panel 11. A plurality of reinforcing members 30 may be installed, but one is preferable from the viewpoints of weight reduction and material cost reduction. The reinforcing member 30 is provided from the longitudinal center of the frame 20a to the longitudinal center of the frame 20b. That is, the solar cell module 10 includes one reinforcing member 30 provided along the short side direction through the central portion in the long side direction of the solar cell panel 11. For example, the reinforcing member 30 is provided between the frame 20c and the frame 20d and may be provided along the long side direction of the solar cell panel 11. However, from the viewpoint of weight reduction, material cost reduction, and the like, It is preferable to be provided along the side direction.

補強部材３０は、長手方向一端部がフレーム２０ａの内鍔部２４ａ上に配置され、長手方向他端部がフレーム２０ｂの内鍔部２４ｂ上に配置されている。即ち、補強部材３０の長さは、フレーム本体２１ａ，２１ｂの間隔よりも短く、内鍔部２４ａ，２４ｂの先端同士の間隔よりも長い。補強部材３０の長さは、取り付け性等の観点から、フレーム本体２１ａ，２１ｂと接触しない長さに設定されることが好ましい。補強部材３０の幅は、特に限定されないが、例えばフレーム本体２１ａ，２１ｂの幅よりも長く、フレーム本体２１ａ，２１ｂの幅の５倍に相当する長さよりも短い。補強部材３０は、ボルト４０（図２参照）を用いて内鍔部２４ａ，２４ｂにそれぞれ固定されることが好適である。   The reinforcing member 30 has one end portion in the longitudinal direction disposed on the inner flange portion 24a of the frame 20a, and the other end portion in the longitudinal direction disposed on the inner flange portion 24b of the frame 20b. That is, the length of the reinforcing member 30 is shorter than the interval between the frame main bodies 21a and 21b and longer than the interval between the tips of the inner flange portions 24a and 24b. The length of the reinforcing member 30 is preferably set to a length that does not come into contact with the frame main bodies 21a and 21b from the viewpoint of attachment properties and the like. The width of the reinforcing member 30 is not particularly limited. For example, the reinforcing member 30 is longer than the width of the frame main bodies 21a and 21b and shorter than the length corresponding to five times the width of the frame main bodies 21a and 21b. The reinforcing member 30 is preferably fixed to the inner flange portions 24a and 24b using bolts 40 (see FIG. 2).

図２は、図１中のＡＡ線断面図である。図２に例示するように、フレーム２０ａは、中空の角柱形状を有するフレーム本体２１ａと、フレーム本体２１ａ上に立設した鉤部２２ａとを有する。フレーム２０ａは、上述のようにフレーム本体２１ａの下部からモジュールの内側に張り出した内鍔部２４ａを有する。なお、フレーム本体２１ａは、内鍔部２４ａと太陽電池パネル１１の裏面との間に補強部材３０の長手方向端部を挿入可能な上下方向長さを有する。換言すると、補強部材３０の上下方向長さは、内鍔部２４ａと太陽電池パネル１１の裏面との間隔よりも短く設定される。   2 is a cross-sectional view taken along line AA in FIG. As illustrated in FIG. 2, the frame 20 a includes a frame main body 21 a having a hollow prismatic shape, and a flange 22 a erected on the frame main body 21 a. As described above, the frame 20a has the inner flange portion 24a projecting from the lower portion of the frame main body 21a to the inside of the module. The frame main body 21a has a vertical length in which the longitudinal end of the reinforcing member 30 can be inserted between the inner flange 24a and the back surface of the solar cell panel 11. In other words, the vertical length of the reinforcing member 30 is set to be shorter than the distance between the inner flange portion 24 a and the back surface of the solar cell panel 11.

鉤部２２ａは、フレーム本体２１ａの上面の外側から上方に延び、途中でモジュールの内側に折れ曲がって断面略Ｌ字状に形成されている。そして、フレーム本体２１ａと鉤部２２ａとの間には、太陽電池パネル１１の端縁部を挿入可能な隙間である内溝２３ａが形成されている。図２に示す例では、フレーム２０ａの幅方向に沿った鉤部２２ａの長さが、フレーム本体２１ａの幅と略同一である。   The flange portion 22a extends upward from the outside of the upper surface of the frame main body 21a, and is bent in the middle of the module and formed in a substantially L-shaped cross section. And between the flame | frame main body 21a and the collar part 22a, the inner groove 23a which is a clearance which can insert the edge part of the solar cell panel 11 is formed. In the example shown in FIG. 2, the length of the flange 22a along the width direction of the frame 20a is substantially the same as the width of the frame body 21a.

内鍔部２４ａは、例えばフレーム本体２１ａの下端部から延出し、フレーム本体２１ａの内側面に対して略垂直に形成される。内鍔部２４ａは、太陽電池パネル１１の裏面と略平行に延びることが好適である。本実施形態では、上述の通り内鍔部２４ａに対して補強部材３０がボルト４０を用いて固定される。このため、内鍔部２４ａにはボルト４０が挿通される貫通孔２５ａが形成される。貫通孔２５ａは、補強部材３０の各脚部３１に対応して２つ形成されている。   The inner flange portion 24a extends from, for example, the lower end portion of the frame main body 21a and is formed substantially perpendicular to the inner side surface of the frame main body 21a. The inner flange portion 24a preferably extends substantially parallel to the back surface of the solar cell panel 11. In the present embodiment, the reinforcing member 30 is fixed to the inner flange portion 24a using the bolt 40 as described above. For this reason, a through hole 25a through which the bolt 40 is inserted is formed in the inner flange portion 24a. Two through holes 25 a are formed corresponding to the respective leg portions 31 of the reinforcing member 30.

以下、図３及び図４をさらに参照しながら、補強部材３０について詳説する。図３は図１中のＢＢ線断面図、図４は補強部材３０の斜視図である。   Hereinafter, the reinforcing member 30 will be described in detail with further reference to FIGS. 3 and 4. 3 is a cross-sectional view taken along the line BB in FIG. 1, and FIG. 4 is a perspective view of the reinforcing member 30.

図２〜図４に例示するように、補強部材３０は、一対の脚部３１と、各脚部３１にそれぞれ立設する一対の立壁部３２と、各立壁部３２の上端部同士を連結する天板部３３とを備える。脚部３１は、上述の通りフレーム２０ａ，２０ｂの内鍔部２４ａ，２４ｂにそれぞれ固定される。そして、立壁部３２が太陽電池パネル１１の裏面に対して略垂直に配置され、天板部３３が太陽電池パネル１１の裏面に近接又は接触した状態で当該裏面に沿って配置される。太陽電池パネル１１に受光面側から荷重が加わった場合、即ち太陽電池パネル１１に正圧が加わった場合、その荷重は天板部３３、立壁部３２に伝達され、脚部３１が固定されているフレーム２０ａ，２０ｂによって支持される。   As illustrated in FIGS. 2 to 4, the reinforcing member 30 connects a pair of leg portions 31, a pair of standing wall portions 32 erected on each leg portion 31, and upper ends of the standing wall portions 32. A top plate portion 33. As described above, the leg portion 31 is fixed to the inner flange portions 24a and 24b of the frames 20a and 20b, respectively. And the standing wall part 32 is arrange | positioned substantially perpendicularly with respect to the back surface of the solar cell panel 11, and the top-plate part 33 is arrange | positioned along the said back surface in the state which adjoined or contacted the back surface of the solar cell panel 11. When a load is applied to the solar cell panel 11 from the light receiving surface side, that is, when a positive pressure is applied to the solar cell panel 11, the load is transmitted to the top plate portion 33 and the standing wall portion 32, and the leg portion 31 is fixed. Supported by the frames 20a and 20b.

補強部材３０は、１枚の金属板によって構成されていることが好ましく、１枚の金属板を曲げ加工して製造することができる。補強部材３０は、１枚の金属板を折り曲げて製造可能な構造を有するため、例えば押し出し成形法よりも安価に製造できる。詳しくは後述するが、補強部材３０の長手方向両端部には金属板の一部を切除して切り欠き３５を形成することが好ましい。   The reinforcing member 30 is preferably composed of a single metal plate, and can be manufactured by bending a single metal plate. Since the reinforcing member 30 has a structure that can be manufactured by bending a single metal plate, it can be manufactured at a lower cost than, for example, an extrusion molding method. As will be described in detail later, it is preferable to form a notch 35 by cutting away a part of the metal plate at both ends in the longitudinal direction of the reinforcing member 30.

脚部３１は、補強部材３０の下端部に位置し、補強部材３０の長手方向全長に亘って形成されることが好適である。脚部３１は、例えば平面視略矩形状の平坦な板状部分であって、太陽電池パネル１１の裏面と略平行に配置される。脚部３１は、補強部材３０の幅方向両側に補強部材３０の長手方向に沿って設けられている。本実施形態では、２つの脚部３１が各立壁部３２の下端部から互いに反対方向に延びている。この場合、例えば補強部材３０の幅方向片側に偏って作用する荷重に対する耐久性が向上する。２つの脚部３１は、互いに異なる形状、寸法を有していてもよいが、互いに略同一の形状、寸法を有することが好ましい。   The leg portion 31 is preferably located at the lower end of the reinforcing member 30 and formed over the entire length of the reinforcing member 30 in the longitudinal direction. The leg portion 31 is a flat plate-like portion having a substantially rectangular shape in plan view, for example, and is disposed substantially parallel to the back surface of the solar cell panel 11. The leg portions 31 are provided along the longitudinal direction of the reinforcing member 30 on both sides in the width direction of the reinforcing member 30. In the present embodiment, the two leg portions 31 extend in opposite directions from the lower end portions of the standing wall portions 32. In this case, for example, durability against a load acting on one side of the reinforcing member 30 in the width direction is improved. The two leg portions 31 may have different shapes and dimensions, but preferably have substantially the same shape and dimensions.

脚部３１は、ボルト４０を用いてフレーム２０ａ，２０ｂの内鍔部２４ａ，２４ｂにそれぞれ固定されることが好適である。各脚部３１の長手方向両端部には、内鍔部２４ａ，２４ｂと重なる位置にボルト４０が挿通される貫通孔３４がそれぞれ形成されている。図２に例示するように、補強部材３０は、例えば脚部３１の貫通孔３４と内鍔部２４ａの貫通孔２５ａが一致するように内鍔部２４ａ上に配置される。そして、貫通孔２５ａ，３４に挿通されたボルト４０の軸部にナット４１が取り付けられて脚部３１が内鍔部２４ａに固定される。ボルト４０は、内鍔部２４ａの下から貫通孔２５ａ，３４に挿通され、ナット４１は、内鍔部２４ａ上に取り付けられることが好適である。ボルト４０と内鍔部２４ａの間、ナット４１と脚部３１の間には、一般的にワッシャ４２，４３が設けられる。なお、ボルト４０の代わりにリベットを用いてもよく、また貫通孔２５ａをネジ孔としてナット４１を不要としてもよい。   The leg portion 31 is preferably fixed to the inner flange portions 24a and 24b of the frames 20a and 20b using bolts 40, respectively. Through holes 34 through which the bolts 40 are inserted are formed at both ends in the longitudinal direction of each leg 31 so as to overlap the inner flange portions 24a and 24b. As illustrated in FIG. 2, the reinforcing member 30 is disposed on the inner flange portion 24 a so that, for example, the through hole 34 of the leg portion 31 and the through hole 25 a of the inner flange portion 24 a coincide with each other. And the nut 41 is attached to the axial part of the volt | bolt 40 penetrated by the through-holes 25a and 34, and the leg part 31 is fixed to the inner collar part 24a. The bolt 40 is preferably inserted into the through holes 25a and 34 from below the inner flange portion 24a, and the nut 41 is preferably mounted on the inner flange portion 24a. Washers 42 and 43 are generally provided between the bolt 40 and the inner flange portion 24 a and between the nut 41 and the leg portion 31. A rivet may be used instead of the bolt 40, and the through hole 25a may be a screw hole and the nut 41 may be unnecessary.

立壁部３２は、脚部３１に対して略垂直に形成されることが好ましく、各脚部３１にそれぞれ立設する２つの立壁部３２は互いに略平行に形成される。そして、各立壁部３２は太陽電池パネル１１の裏面に対して略垂直に配置される。天板部３３により連結された一対の立壁部３２が太陽電池パネル１１の裏面に対して略垂直に、互いに間隔をあけて配置されることにより、高い耐荷重性が得られ、太陽電池パネル１１の撓みを高度に抑制することが可能となる。   The standing wall portion 32 is preferably formed substantially perpendicular to the leg portion 31, and the two standing wall portions 32 standing on each leg portion 31 are formed substantially parallel to each other. And each standing wall part 32 is arrange | positioned with respect to the back surface of the solar cell panel 11 substantially perpendicularly. The pair of upright wall portions 32 connected by the top plate portion 33 are arranged substantially perpendicularly to the back surface of the solar cell panel 11 and spaced apart from each other, whereby high load resistance is obtained. Can be suppressed to a high degree.

立壁部３２は、補強部材３０の耐荷重性を向上させるため、脚部３１と略同一の長さを有することが好適である。即ち、立壁部３２は補強部材３０の長手方向全長に亘って形成されることが好ましい。立壁部３２は、長手方向全長に亘って同じ高さ、即ち同じ上下方向長さで形成されてもよいが、好ましくは長手方向中央部よりも長手方向両端部で低く形成される。立壁部３２の長手方向両端部を除く部分は、例えば略同一の高さに形成され、各脚部３１を内鍔部２４ａ，２４ｂにそれぞれ固定した状態で立壁部３２の上端が太陽電池パネル１１の裏面に近接又は接触している。なお、２つの立壁部３２は互いに略同一の形状、寸法を有することが好ましい。   The standing wall portion 32 preferably has substantially the same length as the leg portion 31 in order to improve the load resistance of the reinforcing member 30. In other words, the standing wall portion 32 is preferably formed over the entire length of the reinforcing member 30 in the longitudinal direction. The standing wall portion 32 may be formed at the same height over the entire length in the longitudinal direction, that is, at the same vertical length, but is preferably formed lower at both longitudinal ends than at the longitudinal center portion. The portions excluding both ends in the longitudinal direction of the standing wall portion 32 are formed to have substantially the same height, for example, and the upper end of the standing wall portion 32 is fixed to the solar cell panel 11 with each leg portion 31 fixed to the inner flange portions 24a and 24b. It is close to or in contact with the back of The two standing wall portions 32 preferably have substantially the same shape and dimensions.

立壁部３２は、上述の通り長手方向両端部で高さが低くなっていることが好適である。本実施形態では、補強部材３０が１枚の金属板によって構成され、補強部材３０の長手方向両端部に切り欠き３５が形成されている。そして、補強部材３０の長手方向両端部には天板部３３が形成されていない。即ち、補強部材３０は、天板部３３の長手方向両端から脚部３１及び立壁部３２が当該長手方向に延出した構造を有する。立壁部３２の長手方向両端部の高さｈ１は、例えば長手方向中央部の高さｈ２の３％〜１０％である。この場合、補強部材３０の耐荷重性を確保しながら、補強部材３０の取り付け性を向上させることができる。また、補強部材３０をさらに軽量化することができる。補強部材３０の取り付け方法については後述する。   As described above, it is preferable that the standing wall portion 32 has a low height at both ends in the longitudinal direction. In the present embodiment, the reinforcing member 30 is constituted by a single metal plate, and notches 35 are formed at both ends in the longitudinal direction of the reinforcing member 30. And the top plate part 33 is not formed in the longitudinal direction both ends of the reinforcing member 30. That is, the reinforcing member 30 has a structure in which the leg portion 31 and the standing wall portion 32 extend in the longitudinal direction from both longitudinal ends of the top plate portion 33. The height h1 of both ends in the longitudinal direction of the standing wall 32 is, for example, 3% to 10% of the height h2 of the central part in the longitudinal direction. In this case, the attachment property of the reinforcing member 30 can be improved while ensuring the load resistance of the reinforcing member 30. Further, the weight of the reinforcing member 30 can be further reduced. A method for attaching the reinforcing member 30 will be described later.

立壁部３２の長手方向両端部に位置する上端角部は、外側に向かって湾曲していることが好適である。即ち、立壁部３２の上端角部はＲ面取り加工されており、丸みを帯びている。この場合、例えば補強部材３０の取り付け時に、立壁部３２の上端角部が太陽電池パネル１１の裏面に接触したとしても当該パネルの損傷が発生し難くなる。   It is preferable that the upper end corners located at both ends in the longitudinal direction of the standing wall 32 are curved outward. That is, the upper end corner of the standing wall 32 is rounded and rounded. In this case, for example, even when the upper end corner of the standing wall 32 comes into contact with the back surface of the solar cell panel 11 when the reinforcing member 30 is attached, the panel is less likely to be damaged.

天板部３３は、一対の立壁部３２の上端部同士を連結することで補強部材３０を一体化し、補強部材３０の耐荷重性、取り付け性等を向上させる。補強部材３０は、天板部３３が太陽電池パネル１１の裏面近傍においてパネルの裏面との間に間隔をあけて配置されてもよいが、好ましくは天板部３３がパネルの裏面に略接触した状態で配置される。なお、前者の場合は太陽電池パネル１１に正圧が加わりパネルがある程度撓んだときに、パネルの裏面が天板部３３に接触して支持され、それ以上の撓みが防止される。   The top plate portion 33 connects the upper end portions of the pair of standing wall portions 32 to integrate the reinforcing member 30, and improves the load resistance, attachment properties, and the like of the reinforcing member 30. In the reinforcing member 30, the top plate portion 33 may be disposed in the vicinity of the back surface of the solar cell panel 11 with a space between the back surface of the panel, but preferably the top plate portion 33 is substantially in contact with the back surface of the panel. Arranged in a state. In the former case, when a positive pressure is applied to the solar cell panel 11 and the panel is bent to some extent, the back surface of the panel is supported in contact with the top plate portion 33, and further bending is prevented.

天板部３３は、補強部材３０の上端部において、補強部材３０の長手方向両端部を除く部分に形成されることが好適である。即ち、一対の立壁部３２において補強部材３０の長手方向両端部に位置する部分は互いに連結されていない。天板部３３は、例えば平面視略矩形状の平坦な板状部分であって、太陽電池パネル１１の裏面と略平行に配置され、パネルの裏面に当接する。   The top plate portion 33 is preferably formed on the upper end portion of the reinforcing member 30 at a portion excluding both longitudinal ends of the reinforcing member 30. That is, the portions of the pair of standing wall portions 32 that are located at both ends in the longitudinal direction of the reinforcing member 30 are not connected to each other. The top plate portion 33 is, for example, a flat plate portion having a substantially rectangular shape in plan view, and is disposed substantially parallel to the back surface of the solar cell panel 11 and abuts on the back surface of the panel.

天板部３３は、接着材４４によって太陽電池パネル１１の裏面に接着されていることが好適である。太陽電池パネル１１の裏面に天板部３３を接着することにより、例えば風の吹き抜けによりパネルの裏側から荷重が加わった場合、即ち太陽電池パネル１１に負圧が加わった場合にもパネルの撓みを抑制することが可能となる。太陽電池パネル１１の裏面と天板部３３の上面との間に介在する接着材４４の厚みは、例えば１０μｍ〜１ｍｍ程度である。   The top plate portion 33 is preferably bonded to the back surface of the solar cell panel 11 with an adhesive material 44. By adhering the top plate portion 33 to the back surface of the solar cell panel 11, for example, when a load is applied from the back side of the panel due to wind blow-off, that is, when a negative pressure is applied to the solar cell panel 11, the panel is bent. It becomes possible to suppress. The thickness of the adhesive 44 interposed between the back surface of the solar cell panel 11 and the top surface of the top plate portion 33 is, for example, about 10 μm to 1 mm.

接着材４４には、一般的な乾燥硬化型接着剤、２液硬化型接着剤、湿気硬化型接着剤等を用いることができる。例えば、これら接着剤を天板部３３上に塗布して、太陽電池パネル１１の裏面に天板部３３を接合してもよいが、生産性向上等の観点から、接着材４４はテープ基材の両面に接着剤層が形成された両面テープであることが好ましい。当該両面テープは、例えば界面活性剤を含有する乾燥硬化型の接着剤層を有する。   As the adhesive 44, a general dry curable adhesive, a two-component curable adhesive, a moisture curable adhesive, or the like can be used. For example, these adhesives may be applied on the top plate portion 33 and the top plate portion 33 may be joined to the back surface of the solar cell panel 11, but from the viewpoint of improving productivity, the adhesive 44 is a tape base material. It is preferable that the double-sided tape has an adhesive layer formed on both sides. The double-sided tape has, for example, a dry curable adhesive layer containing a surfactant.

図５は、太陽電池パネル１１の裏側に補強部材３０を取り付ける様子を示す図である。図５に例示するように、補強部材３０は、長手方向両端部が内鍔部２４ａ，２４ｂと太陽電池パネル１１の裏面との間に挿し込まれる。このとき、天板部３３上には両面テープである接着材４４が貼着されていることが好ましい。そして、脚部３１の貫通孔３４に挿通されたボルト４０により補強部材３０が内鍔部２４ａ，２４ｂに固定される。   FIG. 5 is a diagram illustrating a state in which the reinforcing member 30 is attached to the back side of the solar cell panel 11. As illustrated in FIG. 5, both ends of the reinforcing member 30 in the longitudinal direction are inserted between the inner flange portions 24 a and 24 b and the back surface of the solar cell panel 11. At this time, it is preferable that the adhesive material 44 which is a double-sided tape is stuck on the top plate portion 33. And the reinforcement member 30 is fixed to the inner collar parts 24a and 24b with the volt | bolt 40 inserted in the through-hole 34 of the leg part 31. FIG.

立壁部３２は、上述の通り長手方向両端部で高さが低くなっているため、太陽電池パネル１１の裏面に立壁部３２が接触することなく補強部材３０を取り付けることができる。また、立壁部３２の上端角部はＲ面取り加工されているため、上端角部が太陽電池パネル１１の裏面に接触したとしても当該パネルの損傷を防止できる。なお、太陽電池パネル１１を受光面側から吸引して受光面側に撓ませた状態で補強部材３０を取り付けてもよい。或いは、補強部材３０を太陽電池パネル１１の裏面に接合した後、当該パネルにモジュールフレーム２０を設置することも可能である。   Since the height of the standing wall portion 32 is low at both ends in the longitudinal direction as described above, the reinforcing member 30 can be attached without the standing wall portion 32 contacting the back surface of the solar cell panel 11. Moreover, since the upper end corner | angular part of the standing wall part 32 is carrying out R chamfering process, even if an upper end corner | angular part contacts the back surface of the solar cell panel 11, the damage of the said panel can be prevented. In addition, you may attach the reinforcement member 30 in the state which attracted | sucked the solar cell panel 11 from the light-receiving surface side, and was bent to the light-receiving surface side. Alternatively, after the reinforcing member 30 is joined to the back surface of the solar cell panel 11, the module frame 20 can be installed on the panel.

図６は、実施形態の他の一例である補強部材５０を示す断面図である。図６に例示するように、補強部材５０は、一対の脚部５１、一対の立壁部３２、及び天板部３３を備える点で補強部材３０と共通する。一方、２つの脚部５１は各立壁部３２の下端部から互いに近づく方向、即ち補強部材５０の内側に延びている点で補強部材３０と異なる。この場合、補強部材３０よりも幅を小さくすることができる。脚部５１は天板部３３と上下方向に並んで設けられており、補強部材５０は断面略ロの字形状を有する。脚部５１は、脚部３１と同様に、補強部材５０をフレームの内鍔部に固定するためのボルトが挿通される貫通孔を有することが好ましい。   FIG. 6 is a cross-sectional view showing a reinforcing member 50 as another example of the embodiment. As illustrated in FIG. 6, the reinforcing member 50 is common to the reinforcing member 30 in that it includes a pair of leg portions 51, a pair of standing wall portions 32, and a top plate portion 33. On the other hand, the two leg portions 51 differ from the reinforcing member 30 in that the two leg portions 51 extend from the lower end portions of the standing wall portions 32 toward each other, that is, inside the reinforcing member 50. In this case, the width can be made smaller than that of the reinforcing member 30. The leg portion 51 is provided side by side with the top plate portion 33 in the up-down direction, and the reinforcing member 50 has a substantially B-shaped cross section. Like the leg portion 31, the leg portion 51 preferably has a through hole through which a bolt for fixing the reinforcing member 50 to the inner flange portion of the frame is inserted.

上記構成を備えた補強部材３０の作用効果について、図７に示す従来の補強部材１００と比較しながら説明する。図７に例示するように、従来の補強部材１００は、底板部１０１と、天板部１０２と、それらを接続する壁部１０３とを備え、断面略エの字形状を有する。壁部１０３は、底板部１０１及び天板部１０２に対して略垂直に形成され、底板部１０１の幅方向中央部と天板部１０２の幅方向中央部とを接続している。かかる構造を有する補強部材１００では、太陽電池パネル１１の受光面側から荷重α又は荷重βのような力が加わった場合に、天板部１０２が変形し易く、太陽電池パネル１１の撓みを十分に抑制できないことが想定される。つまり、壁部１０３が天板部１０２の幅方向中央部に設けられているため、天板部１０２の幅方向両端部にかかる荷重を十分に支持することができない。なお、負圧についても同様のことがいえる。天板部１０２の厚みを厚くすれば天板部１０２の変形は抑制されるが、この場合、補強部材１００の重量が増加するという課題がある。また、補強部材１００は金属板の折り曲げ加工では製造できず、一般的に押し出し成形により製造される。   The effects of the reinforcing member 30 having the above-described configuration will be described in comparison with the conventional reinforcing member 100 shown in FIG. As illustrated in FIG. 7, the conventional reinforcing member 100 includes a bottom plate portion 101, a top plate portion 102, and a wall portion 103 that connects them, and has a substantially E-shaped cross section. The wall portion 103 is formed substantially perpendicular to the bottom plate portion 101 and the top plate portion 102 and connects the width direction center portion of the bottom plate portion 101 and the width direction center portion of the top plate portion 102. In the reinforcing member 100 having such a structure, when a force such as a load α or a load β is applied from the light receiving surface side of the solar cell panel 11, the top plate portion 102 is easily deformed, and the solar cell panel 11 is sufficiently bent. It is assumed that it cannot be suppressed. That is, since the wall portion 103 is provided at the center portion in the width direction of the top plate portion 102, the load applied to both end portions in the width direction of the top plate portion 102 cannot be sufficiently supported. The same is true for negative pressure. If the thickness of the top plate portion 102 is increased, the deformation of the top plate portion 102 is suppressed, but in this case, there is a problem that the weight of the reinforcing member 100 increases. Further, the reinforcing member 100 cannot be manufactured by bending a metal plate, and is generally manufactured by extrusion molding.

これに対して、補強部材３０は、太陽電池パネル１１の受光面側から荷重α又は荷重βのような力が加わった場合でも、天板部３３の幅方向両端部を支持する一対の立壁部３２によって天板部３３の変形が防止される。つまり、補強部材３０では天板部３３等の変形が起こり難く、補強部材３０は補強部材１００よりも耐荷重性に優れた構造を有している。このため、補強部材３０の厚みを薄くして、太陽電池モジュール１０を軽量化することも可能である。また、補強部材３０は１枚の金属板を曲げ加工して製造することが可能であり、押し出し成形を余儀なくされる補強部材１００よりも安価に製造できる。   On the other hand, the reinforcing member 30 is a pair of standing wall portions that support both ends in the width direction of the top plate portion 33 even when a force such as a load α or a load β is applied from the light receiving surface side of the solar cell panel 11. The top plate portion 33 is prevented from being deformed by 32. That is, in the reinforcing member 30, the top plate portion 33 or the like is not easily deformed, and the reinforcing member 30 has a structure superior in load resistance than the reinforcing member 100. For this reason, the thickness of the reinforcing member 30 can be reduced to reduce the weight of the solar cell module 10. The reinforcing member 30 can be manufactured by bending a single metal plate, and can be manufactured at a lower cost than the reinforcing member 100 that is forced to be extruded.
